Carcinoma cutáneo de células de Merkel, a propósito de un caso y revisión de la literatura

Abstract

The Merkel cell carcinoma, also known as cutaneous neuroendocrine carcinoma, is a very rare and aggressive neoplasm. It is characterized by its tendency to recurrence, lymph node dissemination and distant metastasis. We present the case of a 88-year-old male patient with a history of basal cell carcinoma in the dorsal region, who presented a large right cutaneous tumor in the right ankle 3 months ago, which produces distant lymph node metastasis. The immunohistochemical study reveals that it is a cutaneous neuroendocrine carcinoma, exeresis is performed with negative histological edges, but after a few months it relapses, so a deeper surgery is performed and it is accompanied by chemotherapy. Emphasis is placed on the aggressiveness and tendency to recurrence of this rare disease that could go unnoticed in centers of less complexity.
